  1. 11. On Vowels : Spectral Features, Related Aspects of Production and Sociophonetic Dimensions

    Detta är en avhandling från Stockholms universitet, Stockholm

    Sammanfattning : The first and major part of this thesis deals with spectral features of vowels and with the distinction of phonetic information from personal and transmittal information also conveyed to listeners by speech sounds. The results of perceptual experiments with synthetic vowels whose fundamental and first formant were varied in frequency suggested that the smaller tonotopical distances between formants (< 6 Bark) are invariant in phonetically idenctical vowels produced by male and female speakers of several languages.

  2. 12. A study on selecting and optimizing perceptually relevant features for automatic speech recognition

    Detta är en avhandling från Stockholm : KTH

    Författare :Christos Koniaris; W. Bastiaan Kleijn; Richard Heusdens; [2009]
    Nyckelord :;

    Sammanfattning : The performance of an automatic speech recognition (ASR) system strongly depends on the representation used for the front-end. If the extracted features do not include all relevant information, the performance of the classification stage is inherently suboptimal. LÄS MER

  3. 13. Sound perception and design in multimodal environments

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :PerMagnus Lindborg; Anders K. Friberg; Daniel Västfjäll; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; sound; perception; design; multimodal; environment; soundscape; music; listening; crossmodal; psychoacoustics; psychophysiology; personality trait; emotion; appraisal; aesthetics; colour; correlation; regression; classification; sonification; Speech and Music Communication; Tal- och musikkommunikation;

    Sammanfattning : This dissertation is about sound in context. Since sensory processing is inherently multimodal, research in sound is necessarily multidisciplinary. The present work has been guided by principles of systematicity, ecological validity, complementarity of  methods, and integration of science and art. LÄS MER

  4. 14. Funktionella aspekter på satsintonationen i svenska

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Iréne Johansson; []
    Nyckelord :HUMANIORA; HUMANITIES;

    Sammanfattning : The present work is an investigation of the function of sentence intonation in Swedish for conveying information of various kinds: semantic-syntactic (distinguishing .declarative and interrogatory yes/no sentences) , stylistic (on the character of the speech situation), and dialectal information (on the regional background of the speakers).

  5. 15. Methods for Objective and Subjective Video Quality Assessment and for Speech Enhancement

    Detta är en avhandling från Karlskrona : Blekinge Institute of Technology

    Författare :Muhammad Shahid; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Video Quality Assessment; No-Reference Methods; Reduced-Reference Methods; Subjective Experiments; Speech Enhancement; Adaptive Gain Equalizer;

    Sammanfattning : The overwhelming trend of the usage of multimedia services has raised the consumers' awareness about quality. Both service providers and consumers are interested in the delivered level of perceptual quality. The perceptual quality of an original video signal can get degraded due to compression and due to its transmission over a lossy network. LÄS MER
